Do You Realize is a pretty fantastic song by The Flaming Lips. If you're in a hurry, or if you're opposed to hippies singing in cemeteries, the video below probably isn't for you. But if you've got the time, this is quite gorgeous...

Do you realize? That you have the most beautiful faceDo you realize? We’re floating in space,Do you realize? That happiness makes you cryDo you realize? That everyone you know someday will dieAnd instead of saying all of your goodbyes, let them knowYou realize that life goes fastIt’s hard to make the good things lastYou realize the sun doesn’t go downIt’s just an illusion caused by the world spinning round
